IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 146,493, dated January 13, 1874; application lul December 5. 1873.

` both commensurate, at all times, with the demand; and to provide a cheap and efficient can bureter; which objects I attain oy constructing the apparatus in the manner fully described hereafter, and as illustrated by the sectional elevation, Figure 1, sectional plan, Fig. 2, and enlarged sectional views, Figs. 3 and 4, of the accompanying drawing.

The annular space between the outer casing A of the apparatus,` and the inner casing B is partly filled with water, in which is immersed the lower edge of a gasometer, D, the latter "beingconnected, by a rod, a, to a valve, E, the "sweat b of which is formed on the under side of an annular chest, F. The interior of this chest isuseparated into two segmental chambers, H andIl., Fig. 4, by partitions el d, and with the former of these chambers communicates the air-supply pipe I, and with the latter the hydrocarbon-supply pipe J.

Air at a uniform pressure is forced into andV through the pipe I bythe ordinary gas-mai chine pump operated by weights; and the hydrocarbon is also supplied under pressure from l an elevated reservoir, K.

-I have found that the proper rela-tive proportions of air and liquid hydrocarbon for the y production of good illuminating-gas are about three parts of the former to one of the latter; hence I have made the air-chamber H of about .three times the capacity of the hydrocarbonchamber H and the former chamber is pro vided with three times as many outlet-aper tures 7u as the chamber H has outlets k. The whole of these outlet-apertures for both chainbers are arranged in a circle directly opposite the valve-seat b, so that all may be opened and closed simultaneously by the valve E, the

Y movement of which, and consequently the regulation of the supply of air and hydrocarbon to the inner casing B, and thence, through a pipe, M, to the carbureter P and gas-pipes beyond, is entirely dependent upon the pressure within the gasometer D, an increase of press-` ure within the latter raising it and closing the valve and cutting off the supply, while a de crease of pressure, owing toan increased demand for gas, lowers the said gasometer and opens the valve.

The proportioning of the supplies of air and hydrocarbon to the apparatus is one of the most important features of my invention, and can be regulated to a nicety by closing some of the apertures k, or by forming additional apertures k, if it be found that the supply of air is in excess, or by reversing this operationl 1f too much hydrocarbon is supplied. The conthrough the pipe M, to the carbureter I), in

which it is absorbed by sponge or other porous substance, s, and the air is carbureted in passing through said saturated substance, asin ordinary gas apparatus of .this class. y

The carbureter P consists of a series ofpipes, t, screwed at their opposite ends into elbows a, so as to form a continuous coil, which is of great strength, can be readily taken apart to obtain access to its interior, and can be read ily increased in capacity by adding additional i sections. n

I claim as my inventionl. A gas apparatus provided with chambers H Hf, communicating with air and hydrocar- 4. A oarbureter in which the pipes t, lled with porous material, are. connected by detachable elbows u, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subseribing Witnesses.
